I just bought a 1999 8 hp, model J8RXEEM. I dealt with the owner's father in picking up and paying for the motor and therefore received absolutely no explanation about the engine at all. Any markings which might have been on the steering handle are long gone. I have had the motor running after some effort but it will not idle. I have a few questions if someone would be kind enough to clarify a few things for me.
Looking at the "steering handle" diagram on Boats.net, there is an "idle adjustment" which is into/inside of a "twist grip" which goes into/inside of a "helix twist grip" all of which pretty much make up the "steering handle" of the motor.
In looking at the motor itself, it would appear that the idle adjustment is inside of the twist grip and is not visible, and that the twist grip goes inside the helix twist grip. Is that correct?
In assuming that the black twist grip (which protrudes about 2 inches out of the helix twist grip) adjusts the idle by rotating the twist grip to port or starboard, how is the twist grip used to adjust the idle? The twist grip appears to have no stop if it is rotated to port, but will stop if rotated far enough to starboard.
The helix twist grip has a line etched into the top of the grip. The steering arm itself has a white dot which faces the helix twist grip. What is the white dot used for in relation to the line on the helix twist grip?
In attempting to start the engine, I made an apparent bad assumption that rotating the helix twist grip to port would give the engine fuel. After starting the engine it appears that rotating the helix twist grip to starboard actually gives the engine gas. Is that correct?
When the engine was running and I rotated the helix twist grip to port the engine would slow and cut off. If I rotated the helix twist grip to starboard the engine rpms would increase.
And, I ordered a service manual for this motor on line. The manual does not go into what I have asked above, however, to my surprise it says that once the engine is broken in, the oil:gas should be 100:1. Is that any opinions on that?
Thanks in advance.
